To all fw/0m t may concer/n.:

Be it known that I, ALBIN l). LorsTnAND, a citizen of the United States, residing at Edmonton, in the Province of AlbertaL and Dominion of Canada, have invented certain new and useful Improvements in Automatic Grain-Shockers, of which the following is a specification.

This invention relates to apparatus for arranging bundles' of grain when delivered from harvesters and binders into shocks or stocks, and commonly known as shookers or stookers, andhas for one of its objects to improve the construction and increase the eiiiciency and utility of apparatus of this character'.

Another object ofthe invention is to provide a device of this character provided with means whereby the bundles of grain which are to forni the' shock or stook are retained in vertical position until" deposited upon the ground, and the head ends of the bundles compressed and the butt ends correspondingly distended to increase the area of the base of the shocks and correspondingly in` crease their stability upon the ground.

another object of the invention is to provide a device of this character including a bundle receiving cage with means for hold- Aing. the several bundles in separated posi.- tions while within the cage, and means for automatically ejecting the bundles when the V' cage is moved into discharging position. f

lilith these and other objects in view, the invention consists in certain novel features of construction as hereafter' shown and def scribed and then speciically pointed out in the claims, and in the drawings, illustrative of the preferred embodiment of the invention.

The improved apparatus comprisesan oblong supporting frame krepresented as a a suitable supportingrframe having carriery wheels, and arranged toibo moved with the' I grain harvester.

whole Aat 10 and mounted upon carrier wheels 11.-12, the carrier wheels l2 being preferably mountedupon swivel hangers 13, so Vthat they may be turned to guide the apparatus.

This frame l0 is left without a traverse member at the rear, so that the apparatus will pass over the shock when the latter is deposited, At the rear end vertical standards 14@ are attached to the'base frame l0 and connected at their upper ends by a` at their forward ends by obliquely directed f members 17 and transverse members `16. At their forward ends vthe side members l() yof the baseframe are connected by a framek 18 including spaced transverse members as illustrated in l, the spaced members of the frame 18 being provided with bear ings 19--20 to receive a shaft 21. The

kdriven from a portion of the driving mechanism of ya grain harvester, the latter not being shown. Attached to the frame l0 are brackets orhangers 32 having suitable bearings carrying an endless slatted belt 33. One ofthe journals of theslatted beltfis extended as shown at 34 and supportedat its outerendy byy a bracket 35 extending from the adjacent bracket 32. Mounted for rotation with the shaft yor journal 34 is a chain wheel 86. and the shaft 34 is likewise provided with a clutch member 37; The clutch memberand chain wheel being rotated with the shaft. Slidably mounted upon the journal 3d is opposing clutch member 38,

bers l0 near their forward ends is a transverse drive shaft 81 having cable pulleys82 in alinement with the cable pulleys 80. Endlesscables 83 are carried over-the pulleys 82 and 80, so that the rotation of the shaft Sl is communicated tothe pulleys 72.

By this arrangement the rotation of the shaft 81 is communicated to the endless belts '76, as will be obvious.

Attached to one of the members l() is a cylinder 84 having a piston 85 and piston rod 86, the latter having a gear raclr 87 engaging a gear pinion 88 on the shalt Si. The cylinder is adapted to receive compressed air to move the piston 85 and its rod 86 and thus communicate motion to the yshaft 8l through the coaction of the rack Si and the pinion 88. Any. suitable container for the compressed air may be employed, but for the purpose of illustration a con'- ventional container of this class is representedr at 94. Any suitable means may be employed for charging the receiver 9a, but 'for the purpose of illustration 'a conventional air pump 89 is shownlor this pur pose. f f

lf preferred a compression pump may be connected tcbe operated bythe binder mechanism of the harvester, but as this feature forms no part of the present invention it is not deemed necessary to illustrate it. f

Leading from the member 9,4 is a supply,

pipe 90 connected .into the suitable threeway controlling valve `91; Conductor pipes 90 and 92 lead from the two way valve and are connected into the opposite ends of the cylinder 8i as shown. TheJ rack contained portion of the piston rod islsupported below the lpinion 88 by an anti-friction roller 92 upon a stud 93 connected to the adjacent portion of one of the members l0, as shown in Fig. 2. Y

The improved apparatus is designed to be coupled in. any suitable manner to a grain binder and harvester, and to be movedover the iield ther'ewith,-with the 'belt 33 arranged to receive the bundles from the binder, but as the harvester andbinder form no part of the present invention it is not deemed necessarv to illustrate them.

The drive chain 36 is ailapted'to be actuated from the sickle shaft of the harvester and rotates the shalt 3i constantly as the harvester and the coupled shocking; apparatus is moved forwardly. and the same is true of the shatld` which is adapted to be coupled to the knetter mechanism of thek binder. f

The member 28 thus rotates constantly, and is held normally in rearward position by the spring 30, with the levers i3-4e and l1 holding the clutch 37-38 open and the endless conveyer belt 33 stationary. l/Vhen the cage is in its forward position the hub 29 of the member 28 couples the interior of the cage to the shalt 2l and rotates it, this movement actuating the levers and starting the endless carrier belt `33, so that the belt operates 'at the same time with the device 61 and its lingers 65 of the cage. When the cage is delivering its load the spring 30 disconnects the clutch Bil-38 and stops the belt 33.

ll/rith an apparatus thus connected the operation is as follows:

Assuming that the cage 55 is coupled relation to the shalt 2l through the coaction of the members 29 and 63, and rotated thereby. This position of the shaft 2l causes the compression of the spring 30 and also causes the levers @mail and il toclose the clutch SPK-38 and rotate the belt 33.

This latter position ofthe cage applies strain to the pull cable il and holds the arms 67 and collars 65 in rearward positiony and likewise holds the tubular member 61 in its rearward position and the fingers 65 in projected position, as shown lullig. l.

Eachlonnjitudinal series of the fingers 65 form a poclret like portion within the cage,

and as the` member 61 and its lingers is f cage, the bound bundles of grain are-fed one at a time into the pockets. When the pockets are'all Vsinoplied the valve 91*v is turned and air admitted to the'eylindeit 84 in the rear of the piston 85. The motion of the piston is thus transmitted to the shaft Si and thence through the cables 76, the latter in turn moving the canje and its contents along the guide member 18a-49 and 5-1-52, as before described, and into vertical or discharging positionas indicated in Fig. 2.

As the cage is thus drawn away from the member 28 the spring 3() by its reaction actuates the levers i3-fli4l and il and opens the clutch 37-38 and stops the belt the latter thus remaining stationary while the page is being unloaded. i y

As the cage is moved into discharging position the tubular member 6l, which is relatively heavy, drops by .eravity until stopped 1 1 along the member 6l carrying the weighted rods 67 therewith and causing them to follow the released bundles yof strain and form a cap to the head ends of the bundlesy and compress them and correspondingly distend the butt ends and thus not only hold the shock or stock intact duringr its descent to a position upon the ground, but also ini creases the stability.

When the gavel or collection of bundles of grain have been discharged, the valve 91 is within the cage and having transverse aper tures, a rod movable within the cage, a plurality of fingers pivoted to said rod and eX- tending respectively through said apertures, anti-friction rollers swingingly supported upon said tubular members and between which said fingers operate, means for moving said receptacle from a horizontal to a perpendicular position, andmeans for withdrawing said fingers when the receptacle as-l sumes a vertical position.
